On sloped properties, soil erosion is a real threat to buildings, roads, and other structures. Retaining walls help stabilize the ground when slopes and elevations change throughout the terrain. It’s important to reinforce soil and decrease its tendency to erode due to weather or settlement processes.

Retaining Walls Help Accommodate:

  • Slopes
  • Dips
  • Inclines

Retaining wall construction manipulates a landscape so it’s more usable, whether as a residential yard or a commercial site. They bring beauty to any property, as well as functionality.

Check out some of the common questions

Do I Need a Retaining Wall?

If you’re building a sunken patio, creating a walkout basement, or facing a drastic change in ground elevation, you might need a retaining wall. They also come in useful for creating terraced gardens in hilly or mountainous terrain, and landscaping focal points.

Do I Need a Permit for a Retaining Wall?

For remodels and new construction alike, retaining walls usually require a permit. Check with your local municipality before breaking ground; it’s also important to have an accurate land survey so you know if there are any utility lines in the path of your worksite.

How Deep Does a Retaining Wall Need to Be?

For every 12 inches of height above ground, a retaining wall should be 1 inch deep. For commercial projects, sometimes retaining walls are required to be a minimum of 6 inches deep. Depth can vary based on the materials used and the type of retaining wall being built.

How Strategic Fence can help

When we develop a design and installation strategy with you for a retaining wall, we’ll typically use pressure treated lumber that is available in olive green or brown colors. We use a wood preservative to extend the life of the timbers so they withstand the elements for years to come.

Usually, the timbers we use in retaining walls are 6 inches x 6 inches, but we can build a wood retaining wall with 6 inch x 8 inch or 8 inch x 8 inch timbers.


There are a variety of retaining wall systems, including:


  • Crib Walls
  • Solid Walls
  • Steps (that act as retaining walls)
  • Cantilever Walls
  • Piled Walls
  • Hybrid Wall Systems

The type you choose for your home improvement or commercial project will depend on what type of landscape you’re currently working with. If you need help determining the best type of retaining wall for your Colorado property, get in touch with Strategic Fence today.

Learn more about the walls we design and install below.

Crib Walls

This design is very strong because it is essentially one big box filled with 2″ – 4″ diameter washed rock. As a type of gravity wall, they are constructed of interlocking timbers that form boxes.

The boxes are then filled with drainage materials such as crushed stone or coarse rock. The rock allows groundwater to pass through the crib retaining wall, which takes hydrostatic forces out of the picture. Good drainage should always be coupled with a retaining wall system to prevent water buildup behind the wall.

With crib walls, there can also be a large footprint that will restrict any settling. Not sure if we can tackle the terrain on your property? Our tallest crib wall to date reaches a staggering height of 32 feet.

Solid Walls

Solid walls are better suited for smaller-scale projects, or where there is limited space. Sometimes levels are stepped back and flowers and shrubs are planted to help increase the visual appeal of a solid retaining wall.


Steps can be incorporated into retaining wall construction or free standing. Handrail systems can be added if desired.


With careful design and installation from Strategic Fence, you can create a functional and aesthetically pleasing retaining wall that will make your mountain property more useful, all while maintaining proper drainage. We will work closely with you to craft the exact design that suits all of your needs.

Strategic did fences on three adjacent residences at the same time. They completed job in two days. Showed up on time and did a very professional installation. I would recommend them highly. Great crew.
Robert Sanders
The gentleman very professional during this pandemic. Very historical moment for them to shine and make the client feel very comfortable as they wore masks and socially distanced themselves from me. I have underlying health conditions and I appreciate their professionalism. The office staff is a pleasure to work with, providing prompt updated information. The quality of the fence is worth every penny and in the category of Priceless and perfect. If I could have hugged the employees I would have the fence is absolutely beautiful. Thank you for providing me with the Safety and Security I've been looking for in my backyard!!!!
